IMPROVED GARBURETTBR,

The Schedule referrei to in these Letters Patent andmaking pan of the same Be it known that I, O. F. DUNDERDALE, of the city, county, and State ofNew' York, have invented a new and useful Improvement in Garburetters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specifimtiou, in which Figure l is a side view, partly in section, of my improved carburettor attached to a side-wall gas-bracket.

Figure 2 is a detail sectional view of the heater, taken through the line a: :v, fig. 1.

Similar letters oi"- reference indicate corresponding parts.

proved carburetter for attachn'ient to brackets, chandeliers, pendants, or other gas-fixtures, and which shall he so constructed and arranged that the air to be earburett-ed may be heated by the flame which it is intended to feed; and 7 It consists in the construction and combination of the various parts of the apparatus, as hereinafter more fully described.

A, in the drawing, represents an ordinary side-wall bracket, to which is attached a tube, or pipc, B, leading upward and forward to a point directly over the burner for the hydrocarbon.

The upper end of the pipe B opens into a shallow vessel, G, the interior of which is so divided up by partitions as to force the air to pass through a long wind: ing passage, as shown in fig. 2, so to detain the ail over the flame until it becomes thoroughly heated.

If desired, the heater 0 may be made in the form ofa coil of pipe, its particular form being immaterial, so long as it is so constructed as to detain the air over the flame until it has been sutliciently heated.

From the heater 0 the heated air passes out through the short pipe D, which passes through the top of the small earburetting-vessel, or hydroczuhon-reservoir E, which is suspended from the bracket A, as shown in fig. 1, and which contains the hydrocarbon liquid with which the air is to be carburetted.

The lower end of the pipe D extends to the bottom My invent-ion has for its object to furnish an imor the vessel E,'and its lower part is perforated with numerous small holes, so that the air may escape into and rise through the hydrocarbon-liquid in small streams, causing it to be fully charged with hydrocarbon-vapor.

From the vessel E the carburetted air passes through the pipe F to the burner, where itis consumed in the ordinary manner.

The drawing represents an argand burner, but any kind of a burner may be used with equal advantage.

When an argaud burner is used, the heater 0 should be placed close to the top of'the chimney, so as to partially check the draught through said chimney, and detain the burning vapor until it has been fully consumed, thereby increasing the brilliancy of the flame.

The pipe F may be made jointed or not, as may be desired or convenient, according to the kind of burner used, and the particular construction of the apparatus.

A very great advantage of this apparatus is, that the heated and carburetted air passes through so short a spa'cethat it reaches the burner while still heated, and thus prevents the possibility of the pipes becoming clogged by the condensation of the hydrocarbon-vapor.

The air is forced through the ordinary gas-pipes by any of the ordinary air-pumps or blowers used for such purposes.

Having thus uescuueu 11:1 invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the pipe B, heater 0, pipe I), carburotting-vessel E, and pipe F, to conduct the carburettcd air to the burner, with each other and with an ordinary gas-fixture, substantially as herein shown and described, and for the purpose set forth.

' 2. An arrangement of mechanism, by means of which the air to' be carburetted is heated by the flame which it is designed to feed, substantially as herein shown and described, and for the purpose set forth.
